摘要： When switching between a DVD-video mode and a DVD-audio mode in a DVD-A/V player, a current video frame is stored in a current display buffer portion of the memory during the DVD-video mode. The DVD-A/V player is paused in the DVD-video mode and set in the DVD-audio mode. If it is determined that the current display buffer portion of the memory is a reserved display buffer portion of the memory, then the current video frame is copied to a reconstructed display buffer portion of the memory. At least the current display portion of the memory is designated as an ASV buffer and a frame buffer management scheme is changed so as to preserve the ASV buffer.

摘要： An on screen display (OSD) method and apparatus is provided for controlling an on screen display generator with a reduced instruction set processor to advantageously sort and link multiple OSD windows for a video display. More particularly, an on screen display (OSD) analyzes a list of OSD window starting points by sorting into the order of starting points by iteratively sorting small groups of starting points, and linking the OSD window data to correspond to the iteratively sorted starting points. Specifically, a list of eight starting points are sorted in groups of four six times (i.e., first four, last four, middle four, first four, last four, and middle four), achieving processing speed advantages.

摘要： A dynamic allocation of available ASV buffer memory space is performed on each pack in a DVD-A bitstream one pack at a time. Concurrently, an ASV buffer table is updated for each type of data pack currently being processed. The ASV buffer table includes pointers corresponding to the various fields that form a particular ASV frame. In this way, only that memory that is required to store a particular ASV frame is used thereby allowing the ASV buffer memory to be configured on the fly in such a manner as to efficiently store the required ASV frame data. When a particular ASV frame is to be displayed, or otherwise processed, the ASV buffer table is accessed, and the particular pointers for a specific ASV frame are looked up and used to access the desired ASV frame.

摘要： A display master control (200) apparatus and method is provided for controlling a digital video pipeline within a reduced instruction set processor (120) for performing field-level control of the post filter 110, includes field/frame filtering display with up a four-tap multi-phase filter, MPEG1 standard image format (SIF) interpolations, on-the-fly aspect ratio switch, on-the-fly letter box and pan scan switch, video fade-in/out, multiple picture/jacket picture display, and multiple angle-picture display. Display master control 200 sets up horizontal and vertical filters (134, 136) for display line control (176).
